Question

Calculate the increase in potential energy of a 60.0-kg man who climbs a ladder 10.0 meters high

Answer 1

5,880 J ≈ 5,900 J

Take account for the significant figures.

Answer 2

Potential energy = (mass) · (gravity) · (height)

PE = (60 kg) · (9.8 m/s²) · (10 m)

PE = (60 · 9.8 · 10) · (kg · m²/s² )

PE = 5,880 joules
